====Sabellid polychaetes====
The [[Sabellidae|sabellid polychaetes]], or feather duster worms, have cartilage tissue with cellular and matrix specialization supporting their tentacles. They present two distinct extracellular matrix regions. These regions are an acellular fibrous region with a high collagen content, called cartilage-like matrix, and collagen lacking a highly cellularized core, called osteoid-like matrix. The cartilage-like matrix surrounds the osteoid-like matrix. The amount of the acellular fibrous region is variable. The model organisms used in the study of cartilage in sabellid polychaetes are ''Potamilla'' species and ''[[Myxicola infundibulum]]''.<ref name="ColeHall2004" />
